"And we wait for them there?"

"Yes. Take them unawares. Susie will probably be on our side, and we can plan something with her.... Of course this is all only theory. Maybe there isn't a thing in it. That gang was slick; they seemed to know how to drop right off the face of the earth. And I believe this man may be the cleverest of them all. He was quiet; it's the boasting kind, like Susie's husband, who usually get caught first.... So you can see why I don't want any of the police along."

"We better take plenty of food, though," remarked Dot.

"We will take some—but don't forget that we can easily fly back to the coast each night. The island is only a few miles out—it's nothing in a plane."

"True," admitted the other.

"And we'll keep our room here at the hotel, for we want some place as headquarters. We'll put a few over-night necessities into my bag."

"O.K. I'll order a roast chicken and a chocolate cake from the dining-room tonight."

"Oranges, too," added Linda. "They always taste so good. I mustn't forget to fill my thermos-bottles, either."

They went to bed early that night, in order to get a good start on the following morning. Dot, who was particularly enthusiastic about the chocolate cake, carried the basket of food, while Linda took the handbag. They arrived at the City Hall immediately after breakfast, and were ushered right into Captain Magee's office.

"No news of the fourth man yet," he said, after he had greeted Linda and been introduced to Dot. "But I've sent out a call for him by radio, so that all ships are to be warned to be on the look-out for a fellow of his description."
